Anatomical terminology

The arcuate popliteal ligament is an Y-shaped extracapsular ligament of the knee.[1][2]: 138  It is formed as a thickening of the posterior fibres of the joint capsule of the knee.[2]: 138  It reinforces the knee joint capsule inferolaterally.[3]

Anatomy[edit]

From its fibular attachment, the ligament extends superomedially over the tendon of the popliteus muscle, spreading out[3] superficial to the posterior aspect of the tendon.[3][2]: 134 

Attachments[edit]

Its inferior attachment is at the posterior aspect of the head of the fibula.[1][2]: 138 [3]

It has two superior attachments:

  • The medial part of the ligament extends superficial to the tendon of popliteus muscle[2]: 138  to attach at the posterior part of the intercondylar area of tibia.[3][2]: 138 
  • The lateral part forms a separate band that extends to the posterior part of[3] the lateral condyle of femur[3][2]: 138  alongside the tendon of popliteus muscle.[2]: 138
